My thinking was the 2.2 or mitsu turbos for a smaller engine could be a more economical way to pressurize the /6 over a $1200 larger single turbo would cost?

Should be good to go. The nice thing about a slant six is everything is on one side of the motor making it really easy to mount and connect everything.

The mitsus are way to small, 2 garrets would be good for 500 whp though and are far more durable.

It looks like, in the prior picture, that teh 2 turbos are tangential housings but mounted so they are hanging down. Perhaps flipping them over and rotating the CHRA and compressor would get the turbo high enough to get away from the starter? Might move it up 2-3"? That will surely cause other hurdles, though (it always does).
